The Transportation Security Administration (TSA) is preparing for intense pressure at airports, with the busiest day forecast to be Sunday, July 6, when more than 2.9 million flyers are expected to pass through security checkpoints — the highest in TSA’s history.

• Denver International (DEN) – one of the top three busiest for July 4 flyers
• Dallas/Fort Worth International (DFW) – heavy activity on July 2 and July 6
• New York’s JFK and LaGuardia (JFK/LGA) – prepare for taxiway congestion and security bottlenecks
• Miami International (MIA) – popular with travelers heading to Latin America and Florida beaches
• Seattle-Tacoma (SEA) – high volume due to proximity to Canadian border
  

TSA is deploying additional screening staff, new AI-powered scanners, and encouraging use of PreCheck, reminding guardians that children under 12 may accompany them in expedited lanes.
